Most project managers build their first schedule during the second and third phases of the project cycle. This critical time allows team leaders to formulate plans based on stated goals and benefits from the identification phase of the cycle. During this period, project managers must break down project elements into as few parts as possible. After that process, team leaders can start putting the pieces together.
Prioritizing tasks at an early stage helps project managers understand the urgency and the importance of project elements. Debating about priorities is an important part of the preparation phase, allowing contributors to make their case for or against project elements. In some situations, project managers may start to craft very basic schedules and timelines to help colleagues debate project priorities more effectively. Skeleton timelines allow participants to see how changes to project scope and methodology can impact launch dates or shipping schedules. Soon after introducing this tool, project leaders often lock down project elements to focus on trimming down resources.
